General Grievous, Supreme Commander of the Confederacy of Independent Systems' Droid Armies, is about to head to Equestria for negotations, but the General is shot down by the villainous Darth Maul and Savage Opress. When his flagship, the Malevolence II, crash-lands, Grievous meets the Mane 6, who then start to befriend the General. Grievous starts to get along with the Mane 6, but the General has someone else to fear instead of Maul and Savage: Starlight Glimmer! She turns the cyborg Commander of Droids into a pony, leaving him to relearn his fighting skills.

Will the General of the Separatist Droid Army be turned back into a cyborg, or will Starlight Glimmer, Maul, and Savage destroy the Separatists and rule the entire galaxy?

Come on! Can't the General have one day off?!

Timelines:

Star Wars: The Clone Wars: Sometime during 20 BBY.

My Little Pony: Friendship is Magic: After the episode "The Cutie Map", in which the Mane 6 defeated Starlight Glimmer.
